Zippo lighter dating

This lighter was made between 19 and is identifiable by what is known as the "Full Stamp".The base has three lines of text and is the only uncoded version to carry the Patent Number 2517191.Dating lighters made at the Canadian factory is a little more difficult, and often confusing, but with a little detective work, many of the clues are there.There is still much work and research to be done, and this page is by no means complete.Originally this was intended as a quality control record, so that lighters returned for repair could be identified as to when they were manufactured and if, for example, a number of lighters were returned with the same fault then Zippo could identify a possible defect in the manufacturing process or even a supplier of one of the components. As there were some alterations to the positioning of the text on the bottom line, some codes were used twice, therefore close attention should be paid to the text on the bottom line for lighters with 7 or 8 dots. 1955-1965 Dating guide The next set of codes used upright lines either side of the word Zippo. Again 8 lines were used for the first year of the series, with one line being removed each year.Even prior to the coding system we can go some way to identifying the approximate year of manufacture, as the stamping on the bottom has changed slightly over the years. From 1936 until 1953 the bottom will have "PAT2032695 MADE IN U. A." Lighters made in 1953-1955 will have PAT 2517191 PAT. PAT 2032695 Lighters (1933 - 1953) PAT 2517191 PAT. On the image below we can clearly see that there are four dots, either side of the word Zippo. 1966-1973 Dating guide From 1974 until 1981 the solidus (now commonly referred to as a forward slash) was used.1953-1955 Bottom Stamp I now want to go back to the first lighters made after WW!!Since 1955, most Zippo lighters have carried a date code stamped on the base.

Codes were not used on the lighters until 1987, so we have to look closely at the bottom stamp and the insert to try to determine the date of manufacture.

The lighters within this timespan can be narrowed down into two groups, mid 1953 to mid 1954 will have a chrome plated steel case, whereas lighters from mid 1954 until late 1955 will have a chrome plated brass case (In order to test this, place a magnet (wrapped in cotton to avoid damage) to the open lid of the lighter.

As the inserts may be steel, a magnet will stick to some brass cases if placed against the body of the lighter.

Zippo Canada opened in August 1949 and was the only place, other than Bradford, where Zippo lighters were produced.

Operations included the final set-up of the lighter case and insert, surface engraving, cleaning, repair clinic, Items such as packaging and instruction pamphlets, were all “Made in Canada” Dates and timelines about these changes, are VERY difficult to nail down to an exact date, but these are fairly close, based on written info by Zippo, as well as other collectors that have taken the time to share their knowledge with me.
